Does Charleston Lake have bears?

What is the 3 bear rule?

• Ontario Parks recommends keeping a clean camp – store all food, garbage, and scented items in bear-proof containers or your vehicle.

How to store food safely at the park

• Use provided food storage lockers if available; otherwise lock food inside your hard-sided vehicle.
• Never keep food, coolers, or toothpaste inside your tent.
• Raccoons are also known to raid campsites – secure everything before bed.

What this means: bear awareness is essential, but raccoons are the more immediate concern. Prepare for both.
